Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 148 words
A film-forming silicone emulsion composition comprising the following components which are mixed and dispersed: (A) a silicone emulsion comprising: (a) an organopolysiloxane represented by the following general formula: wherein R¹'s each represents the same or different C₁₋₂₀ monovalent hydrocarbon group or hydrogen atom; R²'s each represents a hydroxyl group or a hydrolyzable group; R³'s each represents an amino-containing group or an epoxy-containing group; and a, b and c satisfy the relationships of 0 < a < 3, 0 ≦ b < 2, and 0 < c ≦ 1, respectively, containing at least one amino group or epoxy group per molecule; (b) an emulsifying agent; and (c) water; and (B) a hydrolyzable silane containing at least one functional group per molecule wherein said functional group is an amino-containing group if R³ in the component (A) is an epoxy-containing group, or an epoxy-containing group if R³ is an amino-containing group.
Claim 2
Dependent Claim 95 words
A film-forming silicone emulsion composition as claimed in claim 1, which further comprises: (C) a silicone emulsion comprising: (d) an organopolysiloxane represented by the following general formula: wherein R⁴'s each represents the same or different C₁₋₂₀ monovalent hydrocarbon group hydrogen atom; R⁵'s each represents a hydroxyl group or a hydrolyzable group; and d and e satisfy the relationships of 0 < d < 3, 0 < e < 2, and 1.9 < d + e < 2.2, containing at least one hydroxyl group or hydrolyzable group per molecule; (e) an emulsifying agent; and (f) water.
